[0012] Compared with the prior art, the roller-type parallel heating gas furnace of the utility model has the following beneficial effects:

[0013] 1. By injecting air and gas into the burner, the burner can mix the air and gas and ignite them, thereby causing the air-gas mixture to burn and generate heat. By connecting the air valve to the output end of the burner and the opening of the radiant tube to the air valve, the heat generated by the air-gas mixture can flow into the radiant tube through the air valve, thereby causing the radiant tube to heat the workpiece placed on the transmission roller, thereby achieving heat treatment of the workpiece. Because the two radiant tubes are located above the multiple transmission rollers, when the workpiece is placed on the multiple transmission rollers, the two radiant tubes can heat the workpiece from above. When the workpiece is thin, the product can concentrate heat to heat the workpiece, thereby avoiding heat waste. At the same time, it can also improve the utilization rate of gas and reduce the cost of the product. Moreover, by setting the number of radiant tubes to two, the number of radiant tubes can be reduced while still meeting the requirement of heating thin workpieces, thereby reducing the production cost of the product and improving the user experience of the product.

[0014] 2. By winding multiple U-shaped first locking screws around the outside of the air pipe, and passing at least two locking screws through at least two first support seats, the multiple first locking screws can press the air pipe onto the first support seat, thereby avoiding relative displacement between the air pipe and the first support seat, thereby improving the stability of the air pipe; by respectively putting two first locking nuts on the two ends of the first locking screw, and fitting the two first locking nuts to the first support seat, the first locking screw can be fixed on the first support seat, thereby further improving the stability of the air pipe.

[0015] 3. By winding multiple second locking screws around the outside of the gas pipe and passing the multiple second locking screws through multiple mounting plates respectively, the second locking screws can press the gas pipe against the mounting plate, thereby improving the stability of the gas pipe and avoiding relative displacement between the gas pipe and the mounting plate.

[0016] 4. By installing the first bearing on the outside of the first connecting shaft and placing the first bearing in the support groove of the second support seat, the second support seat can support the first connecting shaft, the connecting cylinder and the transmission roller through the first bearing, thereby improving the stability of the transmission of the transmission roller. By making the second support seat, the first bearing and the first connecting shaft all located on the outside of the furnace body, compared to embedding the first bearing in the furnace body, the heat insulation component provided in the furnace body can be used to avoid the first bearing being damaged due to overheating, thereby improving the quality of the product. At the same time, since the second support seat is located on the outside of the furnace body and supports the first bearing through the second support seat, the second support seat is less likely to be deformed by heat than supporting the first bearing through the furnace body, thereby improving the stability of the second support seat supporting the transmission roller. Therefore, the second support seat can support transmission rollers with longer lengths, thereby improving the applicability of the product.

[0017] 5. The transmission shaft drives the multiple second connecting shafts and the multiple transmission rollers to rotate respectively through the multiple first bevel gears and the multiple second bevel gears. Compared with driving the multiple transmission rollers to rotate through sprockets and chains, the rotation of the transmission rollers is more stable, thereby improving the user experience of the product.

[0018] 6. By fixing multiple L-shaped mounting brackets on the side wall of the furnace body, placing one end of the L-shaped protective cover on the multiple mounting brackets, and placing the other end of the protective cover on the mounting seat, the mounting seat and the mounting bracket cooperate to support the protective cover, thereby improving the stability of the protective cover; at the same time, the protective cover is wrapped around the outside of the first helical gear and the second helical gear, so that the protective cover protects the first helical gear and the second helical gear, thereby preventing parts from falling between the first helical gear and the second helical gear, and further preventing the first helical gear and the second helical gear from being damaged.

[0019] 7. By setting the diameter of the transmission roller to 80-150mm, the transmission roller can have a certain strength, so that the transmission roller can support and transmit heavy workpieces, thereby improving the applicability of the product. At the same time, because the transmission roller has a certain strength, when the width of the furnace body is large, the transmission roller will not deform or break during rotation, thereby improving product quality. By setting the width of the inner wall of the furnace body to 2550-5000mm, sufficient working space is created in the furnace body, so that multiple workpieces can be placed in the furnace body at the same time and heated simultaneously, thereby improving product work efficiency.

[0031] By setting the furnace body 10 as a hollow cavity with openings at both ends, the workpiece to be heated can enter the front opening of the furnace body 10 and move out from the rear opening of the furnace body 10; by sequentially passing multiple drive rollers 11 through the two side walls of the furnace body 10, and making the multiple drive rollers 11 rotatably connected to the furnace body 10, the furnace body 10 can support the multiple drive rollers 11, thereby enabling the multiple drive rollers 11 to rotate within the furnace body 10, and then achieving when the workpiece is placed on the drive rollers 11, the rotating drive rollers 11 can drive the workpiece to move. By locating the radiation tubes 12 in the furnace body 10, fixing the ends of the two radiation tubes 12 facing away from the openings on the inner wall of the furnace body 10, and passing the open ends of the two radiation tubes 12 through the side wall of the furnace body 10, the furnace body 10 supports the two radiation tubes 12, thereby improving the stability of the radiation tubes 12; by installing two air valves 13 on the outside of the furnace body 10, and respectively connecting the two air valves 13 with the openings of the two radiation tubes 12, the furnace body 10 can support the two air valves 13, thereby improving the stability of the air valves 13; by installing two burners 14 on the outsides of the two air valves 13, respectively, and connecting the output ends of the burners 14 to the air valves 13, the heat generated by the burners 14 can be injected into the air valves 13. By installing at least two support beams 15 on the outside of the furnace body 10, installing the gas pipe 16 on the at least two support beams 15, and simultaneously connecting the gas pipe 16 to the input ends of the two burners 14, multiple support beams 15 can support the gas pipe 16, thereby improving the stability of the gas pipe 16 and allowing the gas in the gas pipe 16 to be injected into the burner 14. By installing at least two first support bases 17 on the at least two support beams 15, installing the air pipe 18 on the at least two first support bases 17, and simultaneously connecting the air pipe 18 to the input ends of the two gas burners, multiple first support bases 17 can support the air pipe 18, thereby improving the stability of the air pipe 18 and allowing the air in the air pipe 18 to be injected into the burner 14, thereby allowing the burner 14 to mix the air and gas and burn them to generate heat. The exhaust pipe 19 is located outside the furnace body 10 and is connected to the air valve 13 at the same time, so that when the air and gas are mixed and burned, the exhaust gas generated can be discharged through the exhaust pipe 19.

[0032] When using the product, first connect the air pipe 18 to the air source and the gas pipe 16 to the gas source, so that air and gas are injected into the air pipe 18 and gas pipe 16, respectively. Then, place the workpiece to be heat treated on the drive roller 11. Next, open the valves on the air pipe 18 and gas pipe 16 to allow air and gas to flow into the burner 14. Simultaneously, turn on the burner 14, igniting the air-gas mixture and generating heat. This heat is then injected into the two radiant tubes 12 through the air valve 13. Because the two radiant tubes 12 are located above the drive rollers 11, they heat the workpiece placed on the drive rollers 11, thereby heat-treating the workpiece. Furthermore, because the exhaust pipe 19 is connected to both air valves 13, exhaust gas generated by the mixture and combustion of air and gas is discharged through the exhaust pipe 19. After the workpiece has been heated for a period of time, the drive roller 11 is rotated, causing it to move the workpiece, thereby removing it from the furnace body 10.

[0033] With the above structure, air and gas are injected into the burner 14 so that the burner 14 can mix the air and gas and ignite them, thereby enabling the mixture of air and gas to burn and generate heat; by connecting the air valve 13 to the output end of the burner 14, and connecting the opening of the radiation tube 12 to the air valve 13, the heat generated by the mixture of air and gas can flow into the radiation tube 12 through the air valve 13, thereby enabling the radiation tube 12 to heat the workpiece placed on the transmission roller 11, thereby achieving heat treatment of the workpiece. Since the two radiation tubes 12 are located above the multiple transmission rollers 11, when the workpiece is placed on the multiple transmission rollers 11, the two radiation tubes 12 can heat the workpiece from above the workpiece, so that when the thickness of the workpiece is thin, the product can concentrate heat to heat the workpiece to avoid heat waste, and at the same time improve the utilization rate of gas to reduce the use cost of the product; moreover, by setting the number of radiation tubes 12 to two, it is possible to reduce the number of radiation tubes 12 while meeting the heating requirements of thinner workpieces, thereby reducing the production cost of the product and improving the use experience of the product.

[0034] In the embodiment of the present utility model, as Figures 1 to 7 As shown, the roller-type parallel heating gas furnace also includes: a first locking screw 20 and a first locking nut; the first locking screw 20 is U-shaped, and a first external thread is provided at both ends of the first locking screw 20, at least two first locking screws 20 are wound around the outside of the air pipe 18, and at least two first locking screws 20 respectively pass through at least two first support seats 17; a first internal thread is provided in the first locking nut, and the two first locking nuts are respectively mounted on both ends of the first locking screw 20, and the two first locking nuts are in contact with the first support seat 17.

[0036] In the embodiment of the present utility model, as Figures 1 to 7 As shown, the roller-type parallel heating gas furnace also includes: a mounting plate 21, a second locking screw and a second locking nut; the mounting plate 21 is L-shaped, at least two mounting plates 21 are respectively fixed on the side walls of at least two support beams 15, and the gas pipe 16 is placed on at least two mounting plates 21; the second locking screw is U-shaped, and a second external thread is provided at both ends of the second locking screw, at least two second locking screws are wound around the outside of the gas pipe 16, and at least two second locking screws pass through at least two mounting plates 21 respectively; a second internal thread is provided in the second locking nut, and the two second locking nuts are respectively mounted on the two ends of the second locking screw, and the two second locking nuts are in contact with the mounting plate 21.

[0037] By fixing multiple L-shaped mounting plates 21 on the side walls of at least two support beams 15 respectively, and placing the gas pipe 16 on at least two mounting plates 21, the multiple mounting plates 21 can support the gas pipe 16; by winding multiple second locking screws around the outside of the gas pipe 16, and passing multiple second locking screws through multiple mounting plates 21 respectively, the second locking screws can press the gas pipe 16 onto the mounting plate 21, thereby improving the stability of the gas pipe 16 to avoid relative displacement between the gas pipe 16 and the mounting plate 21; by respectively putting two second locking nuts on both ends of the second locking screw, and fitting the two second locking nuts to the mounting plate 21, the second locking screw can be fixed to the mounting plate 21, thereby further improving the stability of the gas pipe 16.

[0038] In the embodiment of the present utility model, as Figures 1 to 7As shown, the roller-type parallel heating gas furnace also includes: a support plate 22, a connecting tube 23, a first connecting shaft 24, a first bearing 25, a second support seat 26 and a limit screw 28; the support plate 22 is located on the outside of the furnace body 10, and multiple support plates 22 are respectively connected to the two side walls of the furnace body 10, and the support plate 22 is located below the drive roller 11; multiple connecting tubes 23 are respectively mounted on both ends of multiple drive rollers 11, and multiple connecting tubes 23 are located on the outside of the furnace body 10; the first connecting shaft 24 is connected to the connecting tube 23; the first bearing 25 is mounted on the outside of the first connecting shaft 24; a support groove 27 is provided in the second support seat 26, and the support groove 27 is trapezoidal, the second support seat 26 is connected to the support plate 22, and the first bearing 25 is placed in the support groove 27; at least two limit screws 28 are fixed in the support groove 27, and at least two limit screws 28 are located on the outside of the first bearing 25; wherein, there is a gap between the connecting tube 23 and the second support seat 26.

[0039] The furnace body 10 supports the support plates 22 by welding the support plates 22 to the two side walls of the furnace body 10, and the support plates 22 are positioned below the drive rollers 11. The furnace body 10 supports the support plates 22. The furnace body 10 supports the support plates 22 by fitting the multiple connecting cylinders 23 onto the ends of the multiple drive rollers 11, and positioning the connecting cylinders 23 outside the furnace body 10. The drive rollers 11 rotate synchronously with the two connecting cylinders 23, thereby enabling the connecting cylinders 23 to rotate outside the furnace body 10. Furthermore, the first connecting shaft 24 is connected to the connecting cylinder 23, enabling the connecting cylinder 23 to rotate synchronously with the first connecting shaft 24. By connecting the second support seat 26 to the support plate 22, inserting the first bearing 25 onto the outside of the first connecting shaft 24, and placing the first bearing 25 within the support groove 27 of the second support seat 26, the support plate 22 supports the second support seat 26, thereby enabling the second support seat 26 to support the first connecting shaft 24 via the first bearing 25, thereby improving the rotational stability of the first connecting shaft 24, the connecting cylinder 23, and the transmission roller 11, thereby enabling the first connecting shaft 24 to rotate relative to the second support seat 26. By fixing at least two limit screws 28 within the support groove 27 and positioning them outside the first bearing 25, the limit screws 28 can limit the first bearing 25 and the transmission roller 11, thereby preventing the transmission roller 11 from moving horizontally and improving the rotational stability of the transmission roller 11. By providing a gap between the connecting cylinder 23 and the second support seat 26, interference between the connecting cylinder 23 and the second support seat 26 when the connecting cylinder 23 rotates is avoided, thereby improving product quality.

[0040] With the above structure, by inserting the first bearing 25 onto the outside of the first connecting shaft 24 and placing the first bearing 25 within the support groove 27 of the second support seat 26, the second support seat 26 supports the first connecting shaft 24, the connecting cylinder 23, and the transmission roller 11 via the first bearing 25, thereby improving the transmission stability of the transmission roller 11. By locating the second support seat 26, the first bearing 25, and the first connecting shaft 24 outside the furnace body 10, compared to embedding the first bearing 25 within the furnace body 10, the thermal insulation assembly provided within the furnace body 10 can prevent the first bearing 25 from being damaged due to overheating, thereby improving product quality. At the same time, since the second support seat 26 is located on the outside of the furnace body 10 and supports the first bearing 25 through the second support seat 26, the second support seat 26 is not easily deformed by heat compared to supporting the first bearing 25 through the furnace body 10, thereby improving the stability of the second support seat 26 supporting the drive roller 11. Therefore, the second support seat 26 can support a longer drive roller 11 to improve the applicability of the product.

[0042] By connecting the second connecting shaft 29 to a first connecting shaft 24, the second connecting shaft 29 and the first connecting shaft 24 can be rotated synchronously; at the same time, by sleeved the second bearing 30 on the outside of the second connecting shaft 29 and placing the second bearing 30 in the support groove 27, the support groove 27 of the second support seat 26 supports the second connecting shaft 29 through the second bearing 30, thereby improving the rotation stability of the second connecting shaft 29. By connecting multiple connecting frames 31 to one side wall of the box body and fixing the mounting base 32 on the multiple connecting frames 31, the box body supports the mounting base 32 through the multiple connecting frames 31, thereby improving the stability of the mounting base 32; by embedding the transmission shaft 33 into the mounting base 32 and making the transmission shaft 33 rotatably connected to the mounting base 32, so that the mounting base 32 supports the transmission shaft 33, so that the transmission shaft 33 can rotate in the mounting base 32; by respectively sleeveing ​​multiple first bevel gears 34 on the outside of multiple second connecting shafts 29, sleeveing ​​multiple second bevel gears 35 on the outside of the transmission shaft 33, and making the second bevel gears 35 mesh with the first bevel gears 34, so that when the transmission shaft 33 is rotated, the transmission shaft 33 drives the second connecting shaft 29 and the transmission roller 11 to rotate through the second bevel gears 35 and the first bevel gears 34, thereby providing power for the rotating transmission roller 11.
